You have some neat innovative suggestions there. I recently
purchased a pair of small vice grips from Harbor Freight but have not
yet modified them. I will use them for most other holding jobs
but…I still prefer to hold my buffing jobs by hand.
Meanwhile, re fire sale…the best way to get rid of it is still
not to get it. The liberal use of Prip’s or similar anti-firescale
solutions is still the best way…an ounce of prevention you know.
However, if one should get some fire scale/stain…rather than wast
time, polishing materials, and of course, loosing extra metal from
sanding or buffing, here is another way to get rid of it.
Before setting any stones or doing your course polishing, gently
heat the piece (I mean gently…no red) and put it directly into the
pickle (be careful the pickle does not splash onto surrounding items
including yourself). I like the bisodium sulphate pickle but others
probably work as well. Take the piece out, rinse it and then scrub
it with a soft brass brush and soap. Do this three times and all
your firescale/stain should be gone or mostly so.
I recently began requiring all my students go through this cleaning
process because many of them do not have a grasp of how to prevent
scale/stain. This relieves them of a lot of aggreviation and
frustration when they get to the polishing stage.
